The Path to Digital Health Nirvana is Paved with Data Continued from page 21 mHealth users come in different types It’s worth remembering too that mHealth users will generally behave in one of two ways when engaging with an app. These are what I call `initiators`, who want to find a specific piece of information or do a specific task quickly or `investigators` who are looking for general information or education. So, if your target audience are initiators, for instance those wanting to book an appointment, focus on features which enable them to complete tasks in the smallest number of steps and minimise or discard any functionality which does not help do that. If they are investigators, for instance wanting to check symptoms, look at ways to give them fast and easy access to broad information, then identify ways to give them reason to return. Don’t also forget that if developing platforms and apps that will be shared by patients and professionals that the information recorded must be displayed in a way that is useful and advantageous for both parties and enables discussion and action that improves outcomes. You are not alone Realise that no matter how great your mHealth app it won’t be permanently at the centre of the user’s universe. By virtue of the smartphone’s ubiquity, something is going to distract or interrupt the user of your app - either in their surroundings or from the phone itself. Keeping your mHealth app simple, intuitive with a clean, clear interface makes it less hard work for the user and allows the task to be completed faster so making them less likely to need to disengage from your app to do other things. But in the real word that is going to happen at some point so also ensure that it's easy to pick up from where they left off if disturbed. To makes sure this happens enable save states, break larger tasks down into smaller chunks, and put context throughout. Bear in mind that mHealth apps are usually part of a more connected technology service offering (or at least should be) and therefore data ubiquity across devices and form factors is key. Deciding on the amount and type of data to store on the device vs storing in the cloud is important as it can effect performance as well as impact on security and usability. A design is never perfect As the mobile marketplace constantly innovates treat your mHealth apps and platforms as a continuously evolving entities, using data from analytics, user feedback, and advances in technologies to constantly appraise and improve the experience. Don’t ever ignore any piece of feedback that comes your way. There is, however, a point where change becomes counter-productive. Once the app has achieved a critical mass of acceptance it needs to be stabilised before the early majority of users will commit to it. Would I really use this? Don’t develop in a healthcare bubble. Look outside of the field of mHealth for the best in consumer apps and see what features could be adapted for the health 6&RW6W"गN(
